There are supposed to be something like a million (maybe there are several million) species of inhabitants living on the earth. The human species is one of these. Not more than a few thousand of these species are seriously advantageous to men. The harmful and useless species are many times more numerous than the helpful. Now, if the 999,999 non-human species were made for the human species, why were the hundreds of thousands of species made that are of no possible human importance, and the hundreds of thousands of other species that are a positive injury? And if by some miraculous stretch of imagination the 999,999 species now living on the earth are conceived to have been made for man, why were the 10,000,000 or 15,000,000 of species made that lived and passed away before there was a human being in existence. Perhaps the traditionist will say—accustomed as he is to treat syllogisms with contempt—that they were made to invigorate human ‘faith.’ If the age of the human species be estimated at 50,000 years and the age of the life-process at 100,000,000 years, the time during which man has been on the earth is, when compared with the entire period during which the planet has been tenanted, as 1 to 2,000. And the time during which the earth has been inhabited—immense as that time is when compared with the little span of human history—is also insignificant when compared with the enormous lapse of time during which the planet was slowly cooling and solidifying preliminary to the existence of life. And the entire life of the planet—inconceivably vast as it is—is as nothing compared with that eternity, that duration without beginning or close, during which the sidereal millions have undergone, and are destined to continue to undergo, their countless and immeasurable transformations. It is about as profound to suppose that the earth and its contents, and the suns, stars, and systems of space, were all made for a single species inhabiting an obscure ball located in a remote quarter of the universe as it is to suppose that the gigantic body of the elephant was made for the wisp of hair on the tip of its tail. _Man_ is _not_ the _end_, he is but an _incident_, of the infinite elaborations of Time and Space.
